I have the capabilities to scan an item but can't afford the scanCad software at the moment. I would like to find someone to draw it out in the tormach scancad software and save it in a file i could...

I just put a set of stock bearing back into it to get it running again. (Picked them up locally)
I Found a set of angular contact bearings on line That are the correct size. And rather cheap in...

Has anyone figured out a good replacement for Eldorado Bridgemill Spindle Bearings? One that could handle 6000 Rpms?
I finally toasted mine at 4500 rpms. Running my 2.5hp treadmill dc motor. These...

But I'm not building an Atc around the air wrench design. I went to the air wrench design only to have a usable setup till i can come up with a Fix for the Original Ram setup I had. Mostly due to...

Can't use an Air wrench set up with tormach tooling for an atc setup. But you could easily set it up to work with standard R8 holders. (if you removed the keyway in the spindle housing)
But even...

Just my 2 cents. I modifid Hoss's setup for an sx3. It worked fine for some time. After A few hundred or so of tool changes it started having issues with pulling tools out the holder. re dajusted...

Never mind it's doing it again. Manual or cnc not working.

Forgot to mention it did it in manual and cnc. Made no difference witch I was using.

But of coarse now that i opened my mouth it's not doing it again. Came out this morning and worked every time...

Having a small issue now.

After it sits for a while its a pain to get it going again.
Motor don't come on right away. It acts like it wants to warm before going.
If i leave it on for 10...

I tryed playing with PWM Just to see. 1200 Seems the best with x4 controls
It's 70 rpms low at 400 and 1500 . dead on at 3200 and 3500.

If i lower the number it's dead on at low end but way off...

Sorry I was impatient. It's just been down for to long and am getting antsy.

2 things where causing my issue.

First being your manual is miss labeled on page 77
The page says
1：Signals...

Thanks Neil The high/low did the trick. As for the pwm Syil recommends 1200 on the x4

Ok works in cnc mode with one issue

If I plug in 200rpms and start the spindle it does 3500rpms
And if i plug in 200 rpms it does 3500rpms

How do i reverse that?

So True I've even thought about it for a while. And just went the cheap route and got the the upgrade from Syil.



As always neilw20 Your were right. It turned out it was a loose connection...

After looking closely at the board The first pin is EGND and second pin Is EVCC. So Page 77 of the manual is not correct.

Now At first the motor still did not work. But decided to do the single...

I tried every comb possible on the motor wire same result on all possible choices.

One thing i did find that's weird Is the hall sensor wiring. The spindle control board wiring sheet in the...

Sorry That does Nothing. Motor is wired as the motor Sticker says. And tagged. The hall sensor wires are tagged as the sticker Says.

What would be the true odds that the motor is wired wrong?

Thanks for all the help.

Just ordered those last chips i need.

Front panel issue was due to a bad solder (careless) job to Lm324. Must have gotten a little solder jumping out 2 pins...

Got the Front panel to stop drawing power. Thats back to 6v after changing out LM324 quad opamp. But still have the issue of that one chip and spindle control board.

Yeah been a month of dealing with it. But Haven't spent to much time on it. Since i do still have A Shoptask Eldardo Cnc And another seig Sx3 convert to cnc. I was still able to get some work done....

Wish that was a easy as it sounds. It's not as easy as throw out the cheap Chinese 1hp motors on a shoptask. And replacing them with motors that don't trip out a 20 amp break every other time you...
